The illustrated fastening inserting machine is arranged to supply a plurality of fibre fastenw ings to a gang fastening inserting mechanism of the type disclosed in United States Letters Patent No. 1,707,404, granted April 2, 1929, on an application filed in the name of Fred N. LaChapelle. It is to be understood, however, that the invention is not limited to use in such machines but may, if desired, be used with other types of fastening inserting machines.

The illustrated machine is provided with a frame ill which carries the fastening inserting instrumentalities. An auxiliary frame [2 is secured to the main frame I0, the auxiliary frame [2 carrying the fastening severing and feeding instrumentalities. The main frame It! is pro-- vided with a shaft M which carries a cam l6 for'operating the fastening inserting mechanism in a manner later to be described. .The shaft I4 is connected to a suitable source of power and is intermittently operated in the manner disclosed in the above-mentioned Letters Patent.

The fastening severing and feeding mechanism is operated from a separate source of power, for example, a motor I8, shown in dotted lines in Fig. 1. The motor I8 is provided with a shaft carrying a pulley 28 which is connected by a belt 22 to a pulley 24 loosely mounted on a shaft 26 journaled in bearings 28, 38 in the frame I2 of the machine. The pulley 24 is provided with a flange 32 the inner surface of which forms a fric tion surface which is engaged by a clutch member 34 mounted on the shaft 26. H and the clutch member comprising the flange 32 extending from the pulley are continuously'ro tated. It is necessary, therefore, to provide means for bringing the fastening severing and feeding mechanism into operation at the proper time during the cycle of operation of the machine. To this end mechanism is provided for moving the clutch member 34 into engagement with the inside surface of the flange 32 formed on the pulley 24. It is to be noted that the clutch member 34 is arranged to move axially relatively to the shaft 26 but is prevented from radial movement relatively to the shaft 26 by means of a pin'and slot connection 36. The loose pulley 24 is arranged to rotate relatively to the shaft 26 but is prevented from moving axially thereof by collars 38, 48 secured to the shaft. 'When the clutch member 34 is moved toward the left, as viewed in Fig. 1, into engagement with the "flange 32, the shaft '26 is rotated thereby bringing the fastening severing and feeding mechanism into operation. .This is accomplished by 'moving a lever arm 42 pivotally mounted on a sliding member '44. The sliding member 44 is provided with a forked end into which fits one end of a lever arm 46. The lever arm '46 being secured to the forked end .of the sliding member 44, by a pin 48. The other end of the lever arm 46 is rigidly secured to a vertical shaft 58 which is mounted in bearings 52, 54. The lower end of the shaft 58 is provided with a lever arm 56 which carries a cam roll 58 engaging a cam surface formed on the rear portion of the cam member I6. When the cycle of operation of the fastening inserting instrumentalities is completed, a high point 60 on the cam member I6 engages the cam roll '58 swinging the lever 56 rearw'ardly, thus moving the sliding member 44 rearwardly. Interposed between the lower end of the lever 42, which encircles the shaft 26, and the clutch member 34 is a spring 62 through which movement of the arm of the lever 42 is transmitted to the loose clutch member. In order to insure that the clutch member 34 is moved into engagement with the flange 32 the upper end of the lever 42 is connected to a spring plunger 64. The plunger {64 is provided with an enlarged end portion 66 between which and the frame I2 is interposed a coil spring 68. Thus, when the sliding member 44 is moved toward the left, as above described, the spring 68 is compressed, thus tending to rotate the lever 42 about its fulcrum in a clockwise direction as viewed in Fig. 1. This clockwise movement of the lever '42 is transmitted to the clutch member 34 thereby insuring that the parts of the clutch will be in proper driving contact. The sliding member 44 is moved to the left a distance sufiicient to permit its beveledend 18 to be moved out of a notch or recess H in the hub 12 of a worm gear 14.

The shaft 26 carries a spiral gear 16 which meshes with a spiral gear 18 secured to a shaft The loose pulley 28 a r 88 mounted in vertical bearings 82, 84 in the auxiliary frame I2. The shaft 88 carries a fourtooth worm 86 which meshes with the worm gear 14. The relation of the worm 86 to the gear 14 is such that eight revolutions of the worm 86 will rotate the gear 14 one revolution. Mounted adjacent to the upper end of the shaft 88 is a spiral gear 88 held fast to the shaft 88 by a pin 98. The gear 88 meshes with a spiral gear 92 secured to a horizontal shaft 94 mounted in bearings 96, 98 in the auxiliary frame I2. The shaft 94 carries a spur gear I82 which meshes with -a spur'gear I84'secured to a horizontal shaft I86 mounted in suitable bearings in the auxiliary frame I-2. The spur gear I 84 meshes with a spur gear I88 secured to a shaft H8 mounted in bearings H2 and II4 in the machine frame I2. The shafts I86 and H8 operate the mechanism for feeding fastening material to a shearing block II6 and for operating the mechanism for moving the fastening-s from shearing or severing position into the path of movementof the fastening inserting instrumentalities of the machine.

The shaft I86 is provided with a crank II1 which is connected to a piston I I8 contained in a cylinder I28. At the beginning of the cycle of operation of the fastening forming and feeding mechanism the piston I I8 is in the position shown in Fig. 1 and during the first portion of the cycle of operation is moved downwardly on its intake stroke. The top of the cylinder I28 is provided with an exhaust port I22 to which is connected a pipe I24- which leads to a hole in a block I26. During upward movement of the piston I18 air contained in the cylinder is compressed. At the beginning of the downward movement of the piston II'8 the shearing block I I6 is moved toward the left to bring a fastening receiving hole I28 in the block 'I I 6 into alinement with the path of movement of the fastening material. The hole I26 is thus moved out of alinement with a hole I21 in the block I26, thereby closing the hole "I21 and preventing escape of compressed air. The surface of the auxiliaryframe I2 to which the block I26is secured is carefully ground, as is the top surface of the shearing block I 56, thereby permitting intimate contact between the surfaces which act as a seal to prevent undesired escape of compressed air.

At the time that the piston I I8 begins its downward movement the shear block H6 is moved toward the left under the influence of a spring I38 surrounding a sliding bar 132 secured to the block H6. The other end of the sliding bar I62 is provided with a block I34 which carries a cam roll I36. As shown in Fig. 1, undesired movement of the block I-I6 toward the left is prevented by engagement of the cam roll I36 with a cam surface I38 formed on 'a cam member I48. The cam member I48 is secured to the shaft I86 and rotates therewith. As viewed in Fig. 3, when the shaft I86 rotates in a counterclockwise direction, rotation of the shaft will permit the spring I38 to move the sliding bar I32 toward the left until the low part of the cam is reached. In the illusplaced position and then moves toward the right i to feed a fastening into alinement with the hole I 21 in the block I26. When the fastening is brought into alinement with the hole I21 in the block I26 the piston H8 in the cylinder I28 has .screw I58.

nearly completed its compression stroke. The

fastening .is blown through the hole I28 in the block I I6 and into a hole I42 formed at the center .of an indexing mechanism I44 and then conveyed through tubes to a fastening inserting mechanism 246 as will later be described.

There is secured to the end of the shaft I06 a disk-like block I48 which is provided with a radial groove I50 (Figs. 4 and 5). This groove is T- shaped to receive a substantially T-shaped block I52. The ends of the slot I50 are closed by members I54, I56 which are provided with holes throughwhich pass the non-threaded ends of a The members I54 and I56 are held in position in the slot or groove I50 by pins I60, as shown in Fig. 5. The block I52 is provided with a threaded hole to receive the screw I58. Thus, by turning the screw I58 the position of the block I52 in the slot I50 may be varied to provide for increased or decreased length of feeding movement. When the block I52 is in the proper position it may be locked in that position by means of a set screw I62 which bears against the side of the block I52 and firmly locks it in position. Secured to the block I52 is a crank pin I84 which is provided with an enlarged end portion I66 which fits into a horizontal slot I68 formed in a sliding block I10 (Figs. 1 and 4). The block I10 is provided with a pair of vertical grooves which receive ways I'II, I13 which are formed as a part of the auxiliary frame I2.

The block I10 is provided with a hole through which passes a tube I12 locked in position by a set screw I14. The hole in the tube I12 receives fastening material I16 in the form of paper twine. The'paper twine is in the form of a coil which may be supported in any suitable manner. Secured to the lower end of the tube I12 is a feeddog I18 which is arranged to grip the fibre twine I16 when the dog is moved downwardly but is arranged to release the twine when the dog is moved upwardly. In order to prevent undesired reverse movement of the paper twine I16 there is provided a dog I which is constructed and arranged to permit the paper twine to move downwardly but which grips the paper twine to prevent undesired upward movement of the twine. The feed dog I80 is mounted on a tube I8! and is secured to the block I26 by means of a set screw I82 and is provided with a hole through which the paper twine or fastening material passes. The construction and operation of the feed dog I10 and the dog I80 is described in detail in United States Letters Patent No. 1,802,900, granted April 28, 1931 on an application filed in the names of Fred N. LaChapelle and Fred C. Eastman, to which reference may be had for a more complete disclosure of theseparts. The feeding mechanism above described begins its feeding movement at the time that the shearing block I I6 is returned to its extreme position toward the left as viewed in Fig. 1. The hole I28 in the block I I6 is then in alinement with the tube I8I. The feeding movement of the fastening material I16 continues for substantially 180 of the rotation of the shaft I06. When the feeding movement of the fastening material is completed the slide I I6 is moved toward the right by the cam I40, thus shearing a fastening from the fastening material and transferring the severed fastening into alinement with the hole I21 formed in the block I26. As previously stated, the severed fastening is blown downwardly to the indexing mechanism I44 by compressed air.

The indexing mechanism I44-(Figs. 1 and 2) is arranged to rotate a tube I84 mounted on a rotating carrier I86 to feed severed fastenings into tubes leading to the fastening inserting mechanism 246. As illustrated, the indexing mechanism is arranged to rotate one-eighth of one revolution each time that a fastening is severed and fed into alinement with the hole I21 in the block I26. Referring first to Fig. 2 it is to be noted that av cam I88 is mounted on the shaft H0. The cam surface I90 on the cam I88 engages a cam roll I92 mounted on a slide I94. The slide I94 is mounted in suitable bearings I96, I98 in the auxiliary frame I2. The slide I94 is, provided with a pawl 202 which engages teeth 204 on the indexing member I44. The pawl 202 is normally held between the teeth 204 by means of a spring 206 which is interposed between a collar 208 on the pawl and an extension 2I0 formed as a part of the slide I94, the pawl being mounted in bearings formed in the slide I94 and the extension'2I0. The slide is urged toward the left and the cam roll I92 is heldin engagement with the cam surface I90 by means of a heavy spring 2I2 which surrounds the left-hand end of the slide I94, one end of the spring bearing against the machine frame I2 and the other end of the spring bearing against a nut 2 I4 threaded on the end of the slide I94. When the slide is moved toward the right under the influence of the cam I90 the pawl 202 engages between the teeth 204 of the indexing mechanism I04 and rotates the indexingmechanism one-eighth of one revolution. Upon further rotation of the cam I88 the slide I94 is moved toward the left under'the influence of the spring 2I2 and the pawl 202 is permitted to yield in a direction away from the indexing member to permit the pawl to pass over the top of the next succeeding tooth 2 04. In order to prevent reverse movement of the indexing member I44 there is provided a stop pawl 2I6 similar in construction to the pawl 202 which is yieldingly held against the indexing member by a spring 2I8 engaged at one end by a collar 220 on the pawl 2I6 and at its other end by a bracket 222 secured to the auxiliary frame I2. The indexing mechanism is brought into operation after the fastening severing and feeding mechanism has completed one-fourth of its cycle of operation. That is to say, the indexing operation takes place after feeding movement of the fastening material or paper twine has begun and the indexing operation is completed .before the piston H8 has begun its upward movement and before the fastening feeding operation has been completed. In other words, the indexing operation is completed before a fastening has been severed from the fastening material and before the slide is moved into position to feed another fastening to the indexing means.

The rotating carrier I86 is provided with a sleeve 230 (Fig. 1), fitting into a bearing formed in the auxiliary frame I2 and a lower sleeve 232 fitting into a plate 234 mounted in a bracket 236 secured to the auxiliary frame I2. The plate 234 is provided with a plurality of threaded holes 238 which are arranged to receive threaded couplings 240. As illustrated the plate 234 is provided with eight holes but it is apparent that a different number of holes could be provided if desired, the change in the number of holes, however, being accompanied by suitable changes in the indexing mechanism I44. The couplings 240 are connected to fastening guiding tubes 242 which lead to a nailing block 244 through which the fastening inserting instrumentalities of the machine operate. The tubes 242 are flexible andbent, as shown in Fig. 1, to permit movement of the block 244 to take place without breaking the tubes.

Although the operation of the fastening severing and feeding mechanism has been described in detail it will be well to summarize briefly at this point the operation of this mechanism as a whole. The timing of the parts is clearly shown in Fig. 8 of the drawings. The timing of the, piston H8 is shown by the line P. The piston moves downwardly on its intake stroke during the first 180 of the cycle of operation .and moves upwardly on its compression stroke during the last 180. The timing of the fastening feeding dog I38 is indicated :by the line F. During the first 50 of the cycle of operation the fastening feeding dog H8 is being returned to its initial position and during the next 180 operates to feed the material to the fastening severing and transferring bar 1 i6. The feeding dog then begins its return movement. The operation of the fasteningsevering and transferring bar I I6 is indicated by the line T. During the first 50 of the cycle of operation it is moved to the left by the spring I30 to bring the hole I28 in the bar into alinement with the hole formed in the tube I81. The bar i It then remains stationary during the next 180 of the cycle to receive the fastening material and is then moved to sever a fastening and to transfer the fastening into alinement with the hole 142 in the rotary member I44. The timing of the indexing mechanism I 44 is shown by the line I. The indexing mechanism I44 remains stationary during the first 90 of the cycle of operation and during the next 90 is rotated to bring the fastening receiving hole in the tube 184 into alinement with a hole formed in the intermediate block 234.

The fastening severing and feeding operations, together with the indexing and transferring operations take place in the illustrated machine eight times before the fastenings are driven. As previously stated, the Worm gear 14 makes one revolution while the shaft carrying the worm 86 makes eight revolutions. Since the other parts of the mechanism are connected by gearing having a ratio of one, complete revolution of the worm gear 14 will not take place until these eight fastening severing and feeding operations have been completed. When these operations have been completed and the gear =74 has made one revolution the beveled end 10 of the sliding member 44 will drop into the notch H formed in the hub 72 of the gear 14, thus permitting the clutch member 34 to be moved toward the right, as viewed in Fig. 1, out of engagement with the continuously rotating pulley 24, thus permitting the machine to be brought to a stop with eight fastenings in the block 244 in a position ready to be inserted into a work piece.

The fastening inserting mechanism, as above stated,'is of the type disclosed in Letters Patent No. 1,707,404, above referred to. The machine is provided with a gang of drivers 246 arranged simultaneously to insert paper pegs to attach a rand 248 to aiheel element .250. The machine is provided with a slide (not shown) which :carries a work table 254 on which is placed the heel and rand which are to be pegged together. The slide and work table are moved from loading position to a position below the block 244 in the manner described in said Letters Patent. The block .244 is mounted for movement toward and from the work table 254 to apply clamping pressure to the work. Movement of the block 244 is effected through connections to a cam track 256 formed in the cam member 16. After a work aovaeirr piece has been placed on the table 254 and the treadle is depressed to place the fastening insert ing instrumentalities in operation, the table 254 moves into operating position below the block 1244 which is then moved downwardly to clamp the work. The parts of the machine are now in position to form fastening receiving holes in the work and to insert fastenings in these holes.

The cam member 16 is provided with a cam track 252 into which fits a cam roll secured to one arm of a bell crank lever .264 fulcrumed at 12-65 in the machine frame 10. The other arm of the bell crank lever 284 is provided with a toothed segment 268 which meshes with teeth formed on a driver bar 210. The driver bar 210 is mounted .for reciprocation in ways formed in the front of the machine and is provided with an enlarged bottom portion 2] 2 in which are mounted the fastening inserting tools 246. Referring now to Fig. 6., it will be noted that the block 244 is provided with a plurality of passages .214 which receive the fastening inserting tools .246. The block 244 is also provided with a corresponding number of passages 216 which are enlarged at their upper ends to receive the fastening guiding tubes 2-42. The passages 216 intersect the passages 214 at'a point below the median portion of the block 244. Springs 280 form one side of the lower portion of each passage 216 and are arranged, when the fastening inserting tools 246 are moved upwardly just prior to the fastening inserting stroke, to move the fastenings into the path of movement of the fastening inserting tools 246.

The driver bar 270 is arranged for movement first to form a fastening receiving hole in a work piece and then to insert fastenings in these holes. The cam track 262 is so arranged that the upper limit of the hole forming stroke indicated at A in Fig. 6 is so located that the .lower end of the too-ls 246 does not extend above the lower ends of the .fastenings in the passages 216. The tools are moved downwardly to the full ,line position shown in Fig. 6 to penetrate the work to form fastening receiving holes therein. The driver bar is then moved upwardly to the position indicated at B in Fig. 6 which permits the lower'end of the tools 246 to be moved to a point above the upper ends of the fastenings in the driver passages 216, thus permitting the springs 280 to move the fastenings into the line of drive of the tools 246. The driver bar is then moved downwardly by the cam to-a position indicated at C in Fig. 6 to drive the fastenings into the work.

Although the illustrated fastening inserting mechanism may advantageously be used in connection with the fastening forming and delivering mechanism of the present invention it is to be understood that other types of fastening inserting mechanism could be used if desired. For example, the fastening insertingmechanism disclosed in United States Letters Patent No.
